Describe the bug

#1504 is closed but this seems to be an issue still.

Affected version

gh version 2.95.0 (2026-06-17)
https://github.com/cli/cli/releases/tag/v2.95.0

Steps to reproduce the behavior

1. TZ=UTC gh pr merge N --squash
2. See timezone offset in git log

Expected vs actual behavior

Respect "TZ" env variable. Timezone offset should be "00:00" with TZ=UTC

A little off topic but can timezone be changed in GitHub Web? And if yes, would it affect timezone that github-cli will use?
